2 the dimensions c, a and b indicated on Fig. 2 bear the followingrelation:

Before trimming a cut, the blade 214 with arms 216 is swung about theshaft 211 through about 180 to carry the blade away` from a positionWhere it would be damaged by the saw or knives. The notches 218I permitthe arms 216 to be lifted and the slotsl 263 permit the blade assemblyto be moved toward the left as `viewed in Fig. 2 as well as to be swungcounterclockwise. The cut or work to be lined-up is clamped in adjustedposition as indicated by the blade, be, tween the clamp plate |55 andthepica bar 68.' If necessary a short clamp plate 28| may be inserted toform an extension of the standard clamp plate |55. Further, an anvil 282having a pin 283 adapted to be inserted in a hole in the slide may beprovided, the same being formed n with a bevelled blunt point 284 forengaging the work'. The short clamp plate 28| may have a similar bluntengaging portion 285.

For the particular machine described herein,

when the right'side 286 of the bracket 259 `is on the 60 pica graduationof the pica scale and the point gauge wheel is set at zero, theindicating edge of the line-up blade is in line with the path of thetrimmer knives of the saw. As previously pointed out, the line-up blademay be raised or lowered to accommodate leither type-high or un mountedplates, by turning the knurled head 269.

If a deiinite margin between a type line, or an object on the cut, andthe trimming line is wanted, this margin in picas plus 60 picas (forthev machine herein described) gives the setting v ofthe right side 286of the gauge bracket on l* in either direction b-y manipulating 25Aline-'up gauge 'frcuts-and the pica scale. Assume an eight pica marginis required between a type line on a out and the trimmed edge, then setthe line-up gauge so that the right side 286 of the bracket coincideswith the 68 pica graduation, with the point gauge wheel at zero',line-up the type line on the cut `with respect tothe indicating edge 215of the blade, clamp the cut, swing the line-up blade out of the way andmove the work into contact with the saw blade |9|.-`4 The entire line-upgauge may be moved by pointsfrom any given setting gauge`- wheel.

Although ,one embodiment of the invention has been described in detail,`it is to be understood that the invention is not thus limited, but in,Aricludes modifications and changes that come within the s'cope of theappended claims.

Having thus described the invention, what is claimed asl new and desiredto be secured by i Letters Patent is:

1. A machine of the character described including in combination, a saw,a table having a groove parallel to the cutting plane of the saw., aslide in said groove, a lpica gauge bar rigidly-secured to the front endof the slide at right angles thereto, a bracket slidable on said bar,means to lock said bracket `to. the bar in positions adjustabletomultiples of a point, a line-up blade having an indicating edge parallelto the cutting plane of the saw, means, supporting the blade Yon, thebracket for Vertical adjustment of said edge in a plane perpendicular tothe table said supporting means including a pivot parallel to said edge,and means to clam work for movement with said'slide. the like in-v thepoint cluding in combination, a bracket having a groove adapting thebracket to be placed on a pica gauge bar withv the bar fitting thegroove, a line-up blade having an indicating edge, and means supportingthe blade on the bracket for adjustment of said edge in a verticalplane, said means including a pivot parallel to said edge.

\ 3. A line-up `gauge for cuts and the like including, in combination, abracket having a groove adapting the bracket to be placed on a the pivotbeing parallel to said edge, and a crank pin engaging said armintermediate its ends.

4. The line-up gauge according to claim 3 vwherein the relation of theparts is such that where bequals the distance from the axisl of thepivot to the point where the crank pin engages said arm, a, equals thedistance from said point to said edge, and c equals the length of thecrank.

5. A line-up gauge in accordance with claim 2 wherein said meansincludes a shaft mounted on the bracket for sidewise movement, a framecomprising two arms pivoted on said shaft and carrying said blade attheir free ends, each arm having a notch in its underside intermediatesaid shaft and blade, crank discs having pins engaging in each notch,and means for rotatively adjusting said cranks.

`6. A line-up gauge for cuts and the like including, in combination, abracket having a groove adapting the bracket to be placed on a picagauge bar with the bar tting the groove, a line-up blade having anindicating edge, and means supporting the blade on the bracketvforadjustment of said edge in a plane, said means v where b equals thedistance from the axis of the pivot to the point where the crank pinengagesl said arm, a equals the distance from said point to saidedge,`and c equals the length of the crank. y

7. For use in connection with a composing col room saw or similarcutting machine, a line-up i I gauge for cuts or the like including, incombina'- tion,-a bracket adjustable along the pica gauge bar of saidmachine, a line-up blade having an indicating edge, means supportingsaid blade on said bracket for movement to a preliminary gaugingvposition on top of the work and away from vsuch position prior to thecutting opera-l tion, saidsupporting means also including means foradjusting said blade While in gauging position in a vertical plane toaccommodate'said blade to Work of various heights.

8. For use in connection With a composin room saw or similar cuttingmachine, a line-up gauge for cuts or the like including, in combination,a bracket adjustable along the pica gauge bar of said machine, a line-upblade having an indicating edge, means movably and adjustably supportingsaid blade on said bracket, said means comprising an arm carrying saidblade at its' outer end and provided With a pivotal and slidableconnection with said bracket at its inner end, a crank member carried bysaid bracket and having a readily detachable connection with said arm atan intermediate point thereon; the location oi said point of connectionand the length of said crank being predetermined and cooperating withsaid sliding connection whereby the edge of said gauge is given avertical translatory movement when said crank is rotated to adapt itselfto Work of various heights; and said pivotal connection between thebracket and the arm, and the detachable connection between the arm andsaid crank' arm enabling the gauge to be swung to a retracted positionprior to the operation of the cutting machine. l

9. For use in connection with a composing room saw or similar cuttingmachine, a line-up gauge for cuts or the like including, in combination,a bracket adjustable along the pica gauge bar of said machine, a line-upblade carried by said bracket, said line-up blade having an indicatingedge adapted'to be applied toa portion of the Work, andA means foradjusting said blade in a vertical plane.

10. For use in connection with a composing room saw or similar cuttingmachine,y a line-up gauge for cuts or the'like including, incombination, a bracket adjustable along the pica gaugebar of saidmachine, a line-up blade carried by said bracket and adapted 'to extendover the` Work, said line-up blade having an indicating edgev parallelt0 the cutting plane of the Saw and adapted to be applied to a portionof the Work,4 a straight line motion mechanism for adjusting said bladein a vertical plane, and means for clamping the Work for movement withsaid pica gauge bar.
